have used windows 7 to upgrade to now 10 on my computer since 2016 daily and usually on 24/7. Had power outages suddenly with updates pending and still going strong.

you must be doing something wrong.

you need to do a full read and write on the disk. use a program to write the disk full of 0s and then verify read. UNRAId does this with its preclear function.

Contact the providers with your requirements directly and see what they can offer

unless you’re using storage spaces then don’t use the GUI, you will be limited to 63TB for your pool. you have to use the command line to create it with a higher cluster size to increase that limit to 256TB. Also if one of your drive fails storage space most likely won’t tell you until you do one of those health check commands for your pool

why not just use unraid its exactly what you are looking for, instead of data being striped your files are instead on a single drive in a jbod. caviet for unraid is that its performance for access times and transfer speeds are slower than all other OS solutions like trueNAS, windows storage space etc. due to how smb is implmented on it.

That or use stablebit drivepool if you want to use windows.
